Ellen Gives Robert Pattinson 'Bite Me' Briefs

Twilight star Robert Pattinson can make gaggles of girls scream, but says he's unlucky when it comes to keeping just one girl.

"No one else seems to get into a relationship with me," the 22-year-old Brit, who agrees to being a "relationship type guy," said Tuesday at a taping of The Ellen DeGeneres Show set to air Friday. "It’s really strange."

"People like screaming at me," Pattinson noted. "Actually they like screaming at me in relationships as well. No one wants to commit."

After disagreeing with the newly-minted heartthrob, DeGeneres gave Pattinson, who plays hunky vampire Edward Cullen in the upcoming flick, something that may help him attract a girlfriend: a custom pair of Ellen underwear embroidered with "Bite Me" across the bum.

The film adaptation of Stephenie Meyer's first novel from her bestselling teen saga, which costars Kristen Stewart as mortal heroine Bella, opens Friday as well.
